Technical scheme is used by the utility model solves its technical problem：A kind of camshaft for horizontal engine
Room cover lid, side, which has, in engine block walls, including the case being molded, in described case collects engine
The collecting chamber of gaseous mixture in crankcase, opposite side has an oblique labyrinth chamber in case, and interval is set in described labyrinth chamber
There are several interlaced labyrinth baffle plates, collecting chamber has the air inlet for being passed through gaseous mixture, and labyrinth chamber both ends are respectively equipped with company
The labyrinth import of logical air inlet and the labyrinth outlet of discharge separation gas, are provided with labyrinth chamber and flow back to the machine oil after separation
The oil return opening of engine sump tank.
Specifically, the first L-shaped liner plate is provided with described case, presses close to the first liner plate and have the second liner plate, the
Two liner plates and case inner top surface form described collecting chamber, and the first liner plate and case inner top surface form described labyrinth chamber, air inlet
Mouth is opened on the second liner plate, and there is the machine oil by oil return opening drippage to flow back to engine sump tank between the first liner plate and case
Gap.
Stress caused by larger load causes to damage to case during to bear installation, is used to consolidate with cylinder body on described case
Metal lining is set with fixed connecting hole, the damping of shock insulation Noise Reduction has been provided between the ring flange and case of metal lining
Set.
The beneficial effects of the utility model are：The machine oil that the utility model solves horizontal engine Oil-gas Separation leans on gravity
The problem of oil return, because in the absence of welding structure, assembling and anufacturability are all very high, and simple in construction, parts are few, save
Weight and cost, shock insulation excellent noise reduction effect.
